Sennheiser GSP 300 Review – Best Under Budget Gaming Headphone

No comment

Sennheiser is known for their high-end, premium headphones. Their in-ear and over-ear headsets are mainly designed for audiophiles and are usually expensive. But the high price tag is equally justified by high-quality audio output, comfortability, unique design, and premium peripherals.

Just last year Sennheiser realized that they need to refresh their gaming series and so they introduced two new models. They where Sennheiser GSP 300 and GSP 350. Both of them are really affordable and comes with a very sophisticated design.

Now, when I first saw this new lineup, I was so ecstatic that I just couldn’t resist. Actually, I was just fed up with my HyperX Cloud Stinger and wanted a refresh. So, I just listened to my soul and bought GSP 300 for myself.

Based on my personal experience I can tell you one thing very confidently, in my opinion, this is by far the best gaming headset under $100. Apparently, there are dozens of other competitors, but when it comes to audio quality, no one stands a chance to win.

Sennheiser GSP 300 Review

In this review, I am going to focus on five important factors, and they are sound, build quality, comfortability, noise isolation, and the microphone.

Sound Quality

I just want to say; I’m blown away. It’s simply incredible.

The whole headset is boosted toward gaming experience. It has excellent bass, but it’s not super deep. It’s trailered to make your ears more comfortable so that you could use it for a more extended period of time.

It also works absolutely fantastic for the music. The audio output has a nice pace. They may not be super deep and super punchy, but that’s how I like to listen to most of my playlist.

Personally, I would have preferred a little bit more depth, but overall the sound quality and the audio output is very precise. You get to hear every single possible detail in your game.

To test the audio output, I plugged the headphone into my system and played Need For Speed 2018. After three hours of continuous gaming, I can say it was indeed a new experience for me. I just don’t have any words to share my experience.

Never before I have experienced such sound quality in a headphone under $100. I was able to listen to the sounds of leaves when I drove my car close to the trees. I was able to listen to water splash and sparks. Never ever before I have experienced such details with my HyperX Cloud Stinger which actually is more costlier than this headset. I must also tell you that it doesn’t bleed into the mids and the overall sound output is very structured and precise.

Now note that this headset doesn’t come with virtual 7.1 surround sound effects but it’s upgraded model Sennheiser GSP 350 comes with it. It’s something that I came to know only after buying this headset. But you know what I don’t regret it. This headphone already offers such a great sound quality that I have never experienced before.

Its frequency response ranges from 15,000Hz to 26,000Hz. Furthermore, it has an impedance of 19 Ohms and offers a sound pressure level of 113 dB.

Design and build quality

As you can expect from Sennheiser, GSP 300 comes with a modern visually complex design and rigid body. Unlike other headphone models, the GSP gaming series has a design tailored for gamers.

overall build quality

The whole body is made up of high-quality plastic and is covered in black color. The plastic body helps to keep this headset lightweight without compromising with the rigidness. There are some regions ( top region of the headband holder ) where you will find a bit of grey accent, and I would personally say, its a smart move. There are two blue stripes on the mic which really makes the whole design stand out.

I am quite impressed with its flexibility. In my test, I almost twisted the whole body but couldn’t find a single stretch mark or cracks. That’s really impressive as plastic usually gets those whitish marks when you bend or twist them.

Furthermore, the headband is also solidly built. It has a double wide plastic strip and comes with nice foam padding. The size-adjustable steps within the headband strips are solid and help to keep the earpads in position. The overall clamping force along with the lightweight frame makes it an extremely comfortable gaming headset.


headband comes with foam padding

Coming to the headbands, they are comfortable and are adjustable. The paddings are soft and when you wear the headphone you will feel like nothing is there on your head, at least that’s how I felt. At first, I thought that the foam paddings are not properly sitting on my head. So, I checked myself in the mirror. Guess what, I was wrong. The headband was fitting perfectly, but because of their lightweight frame, I didn’t feel them.

The earpads are extremely comfortable and they just cling to your ears. They are padded with memory foam and even after hours of usages, you will never feel uncomfortable. In my test, I played Need for Speed Payback (2017) for almost 3 hours and even then my ears weren’t sweaty. Once you wear the headphone you will feel that the earpads are engulfing your ears and you will feel nothing else. Additionally, it also stops most of the outside noise as this headset follows the closed-back design approach.

Sound Isolation

earcups are comfortable

One the most impressive elements of this budget gaming headphone is its acoustic isolation. There are various elements which contribute to noise isolation. 1st is the leather-like padding which is simply excellent. Its soft, comfortable and even after prolonged usages your ears won’t get a drop of sweat. 2nd is the angled structure which is crafted especially to fit the ears better.

Harnessing the power of these two design approaches, Sennheiser GSP 300 offers absolutely incredible sound isolation.


I really like the microphone quality. It’s a noise-canceling microphone, and that’s a big plus point for me. If you’re typing on the keyboard, it won’t be super audible as the microphone tries to cancel out all that noise, but very rarely your own voice which you are recording also gets a sort of muffled.

microphone is great and comes with noise cancellation

I have tested it with Dragon Naturally Speaking 13 software, and I must say, it worked really well without reconfiguring my profile settings.

Now you should understand that mic’s recording quality depends a lot on your motherboard and the sound card attached to it. So your mileage may vary based on what sound card or motherboard you plug it in. I have tested it on my custom PC which has Asus Prime Z370-A and the microphone detail was quite better than the system which has Gigabyte Z370 HD3 motherboard. Sound recorded on the computer system with Z370 HD3 has a lot more background hits.

The only drawback is that the microphone is not flexible. If you want to boost the sound by bringing the mic closer to your mouth, you simply cannot do so. Sorry.


volume wheel

I really love the volume wheel on the right side ear pad. The wheel has a slight resistance and feels so much better compared to the volume wheels on the other game series headsets by Sennheiser.

One another cool feature is the inbuilt staple mic mute function. If you want to mute your mic then all you need to do is simply rotate the microphone. Furthermore, the movement is accompanied by a physical and audible click. Overall, it’s so much more convenient than buttons on in-line remotes.

As for the cables, you get the 2-meter cable attached to the headphone. Additionally, you get the combo jack connector in case your system doesn’t have the separate mic and sound port.


Undoubtedly, Sennheiser GSP 300 is perfect under budget gaming headphone. It offers excellent comfort, noise cancellation, and the microphone is super clear but with a bit of less volume pickup.
